The Musings of Simon Green

Who knew installing a mail server could be so perilous?! Just found this in the Exchange 2010 multi-tenant installation check list:

If you have an existing Exchange Enterprise installation and you inadvertently attempted to install using the /hosting switch, you should use Registry Editor to clean up the Exchange Hosting registry. This helps ensure that Enterprise features continue to function properly.

And that’s that. No instructions, no help. Well I hope I never do that! And in fact, how would you even DO that?!

Hello Microsoft support? Yes I seem to have accidentally typed /hosting at the end of the Exchange installer while for some UNHOLY reason trying to install from the command line.

Oh and what happens if you do it the other way you might wonder?

If you attempted to install Exchange, but didn’t use the /hosting switch to prepare Active Directory, you must clean up Active Directory and prepare it again for hosting mode.

Oh sure, I’ll just break out my handy ADSI Edit and go for it shall I? Again, no instructions/points/direction/tips/lifelines/sick bags.

Fucking Windows.
